<p>Hi Even</p>
<p>abidiff tells me:</p>
<pre style="color: rgb(0, 0, 0); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial; word-wrap: break-word; white-space: pre-wrap;">
* Incompatible ABI changes between openjpeg2-2.1.2-4.fc26.x86_64.rpm and openjpeg2-2.2.0-1.fc26.x86_64.rpm. ABI comparison took 0.45 second(s). Please review them.
================ changes of 'libopenjp2.so.2.1.2'===============
Functions changes summary: 9 Removed, 5 Changed, 31 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable
9 Removed functions:

'function OPJ_INT32 opj_mqc_decode()' {opj_mqc_decode}
'function void opj_mqc_destroy()' {opj_mqc_destroy}

'function void opj_raw_init_dec(OPJ_BYTE*, OPJ_UINT32)' {opj_raw_init_dec}
'function OPJ_UINT32 opj_raw_numbytes()' {opj_raw_numbytes}
Is the ABI really 100% compatible?
Thanks

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hi folks,</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">OpenJPEG 2.2.0 is released today:</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><a class="moz-txt-link-freetext" href="https://github.com/uclouvain/openjpeg/releases/tag/v2.2.0">https://github.com/uclouvain/openjpeg/releases/tag/v2.2.0</a></p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">This new release includes a significant number of improvements and bug fixes. In particular:</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">- Multi-threading support at decoding side</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">- Several speed optimisations both at encoder and decoder, and both on Wavelet Transform and Entropy Coding parts. On our test set, a single-threaded execution is now around 20% faster (encoding or decoding).</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">- Huge memory consumption reduction at decoding side (~60% reduction on large images)</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">- Several important bug fixes, in particular the one that was preventing OpenJPEG to encode lossless in some specific situations, as well as those related to mode switches (BYPASS/LAZY, RESTART/TERMALL, etc).</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">- Several security fixes thanks to the inclusion of OpenJPEG in the Google OSS Fuzz project.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Beside that, several improvements have been brought to the project maintenance, like inclusion of benchmarking scripts to compare speed with latest available kakadu binaries.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">And, last but not least, API and ABI are 100% compatible with previous version.</p>
